Zemun is a municipality in the city of Belgrade, Serbia. Zemun was a separate town that was absorbed into Belgrade in 1934. It lies on the right bank of the Danube River, upstream from downtown Belgrade. The development of New Belgrade in the late 20th century expanded the continuous urban area of Belgrade and merged it with Zemun.

The White Bear Tavern is a former kafana in the neighborhood of Ćukovac. First mentioned in 1658, it is the oldest surviving edifice on the urban territory of modern Belgrade. Churches include the Gardoš cemetery church and the Hariš chapel, Saint Nicholas, Saint Archangel Gabriel, and two Roman Catholic churches. Another landmark in Zemun is the Gardoš Tower, which is a memorial tower that was built in 1896.
